This application claims priority from U.S. Prov. Pat. App. 63/266,897, filed Jan. 18, 2022, and is a divisional of U.S. Design Pat. App. 29/797,856, filed Jul. 2, 2021, both of which are hereby incorporated by reference.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to hinges, and more particularly to a hinge for enabling installation of a door or half door on a vehicle, such as off road utility vehicles or the like.

BACKGROUND OF THE INVENTION

Utility vehicles (UTV) or all terrain vehicles (ATV) are often sold without doors, instead employing a mesh-fabric ‘door’ that is removably attached to allow entry and exit from the vehicle, while providing some enclosure when driving to contain any loose items from unintentionally falling out of the vehicle. An example view of such a utility vehicle is shown in FIG. 1 , wherein the vehicle 10 has a frame 12 mounting four wheels 14. In the illustrated version, four seats 16 are provided to accommodate driver/passengers 18. A propulsion engine is mounted to the frame at the rear of the illustrated UTV or ATV. A cargo carrying area 22 may be provided in some models. Mesh half ‘doors’ 24 are detachably positioned at lower portions of openings in the frame to allow driver/riders to enter/exit the vehicle easily, but still allow closure of the ‘doors’. The illustrated UTV has four seats and front and rear mesh doors on each side of the vehicle, but two seat/two ‘door’ models are also provided.

Many users of such vehicles would prefer to have a more solid door structure, either a partial or half door or a full door to provide further protection and minimize debris, splashes or other incursions from outside the vehicle hitting the driver or passengers or entering the frame interior. As such, add on door kits have been developed, such as shown in FIG. 2 , that comprise front and rear doors 26, 28 (driver side doors shown, passenger side doors would typically be mirror images) and attachment hardware for mounting the doors to the frame of the UTV. The attachment hardware might include upper and lower hinge leaf (female) mounts 30, 32, for attachment to the doors, and hinge pin assembly bracket 34 which carries upper and lower bullet hinge pins (male) 36, 38. To mount the doors to the UTV or ATV, the existing mesh ‘door’ is removed, bracket 34 is mounted to the frame of the UTV/ATV, upper and lower hinge pin mounts 30, 32 are mounted to the door(s) at points 40, 42, and the doors are lowered onto the bullet hinge pins. Additional brackets 44 may be provided to assist with securing the bracket 34 to the UTV/ATV’s frame.

Unfortunately, the bullet hinge pins will occasionally break as a result of the stresses put on the pins in use, making the door inoperable, so another way to mount doors to UTVs/ATVs that would be more durable and robust is desirable.

SUMMARY OF THE INVENTION

An object of the invention is to provide a method and apparatus for mounting doors to UTVs/ATVs or other vehicles to replace the stock mesh ‘doors’. An improved bracket mounting a hinged plate is provided for attachment to a door that is to be mounted to the UTV/ATV.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter. It should be appreciated by those skilled in the art that the conception and specific embodiments disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

A preferred embodiment of the invention uses a hinge assembly and lower bracket members to hingedly mount a door to the frame of an UTV/ATV, for providing an improved door structure to the UTV/ATV over the stock mesh doors. A striker bracket may be provided to engage with a latch member to secure the door when in a closed position.

Referring to FIG. 3 , a perspective view of a hinge assembly according to the present invention, the assembly 100 comprises an UTV/ATV frame mounting plate 102 and a door mounting plate 104 where the mounting plate 104 is hingedly mounted to plate 102 via upper and lower hinge members 106, 108. Frame mounting plate 102 is formed as an elongate member with a flat longer rectangular flange portion 110 and a shorter upper portion 112 that is angled away from the plane of the portion 110. The lower end of portion 110 flares out slightly and carries fastener mounting hole 114, while the upper portion 112 carries mounting holes 116, 118 in spaced relation to one another.

Door mounting plate 104 is formed as a flat rectangular plate member 120 with upper and lower hinge mounting flange portions 122, 124 extending at 90 degree angles from the main flat portion plate member 120. Mounting slots 126, 128, 130 and 132 are formed in plate member 120 at spaced locations from one another somewhat centrally positioned in the plate member.

Upper and lower mounting flanges 134, 136 connected to flange portion 110 at a somewhat upper position and a lower position, interact with mounting flange portions 122, 124, with hinge pins 138, 140 hingedly mounting the door mounting frame 104 to frame mounting plate 102, via holes or openings formed in flanges 134 and 136, as well as in flange portions 122, 124, allowing rotational movement of the door mounting frame 104 relative to the frame mounting plate on axis 144, as shown by rotational arrows 146. The rotational mounting details are further described in connection with FIG. 28 , a partial side view taken in the direction of arrow 139 of FIG. 3 and FIG. 29 a partial view taken in the direction of arrow 141 of FIG. 3 .

Hinge pin 138 (and correspondingly 140) passes through holes in flange portion 122 (and 124), held in position by the head of the hinge pin at one end thereof, and by keeper 143, such as an E style clip in the illustrated embodiment, engaged with the end of the pin opposite the head, to keep the pin from sliding out. A bushing 145 lines the openings in flanges 122 and 134, allowing rotational movement of flange 122 relative to flange 134.

The hinge assembly needs to be secured to the frame of the UTV/ATV, so mounting components are also provided. Referring to FIG. 4 , a perspective view of a lower mounting bracket, lower brackets are provided as a left side bracket 148 and right side bracket 148′. The brackets have rear mounting holes 150, 150′ and mounting slots 152, for attachment to the UTV/ATV frame as discussed hereinbelow, and have an angled central region 154 that extends to a mounting plate portion 156 that is oriented to provide a vertically aligned mounting surface. Portion 156 has mounting hole(s) 158 designed to align with fastener mounting hole 114 on the hinge assembly, discussed hereinbelow.

FIG. 5 illustrates an additional mounting component, striker brackets 160 (left side) and 160′ (right side) that have upper and lower mounting holes 162, 164, for attachment to the UTV/ATV frame and carry a striker latch pin 166 (166′) for latching with a corresponding door latch mechanism on the doors. The lower portion of the striker brackets angle slightly to conform to the configuration of the UTV/ATV frame for mounting. The striker brackets are mounted to the frame via fasteners interacting through holes 162, 164.

FIG. 6 and FIG. 7 are perspective views of a rear lower mounting bracket 168, with corresponding mounting holes 170, slots 172 and mounting plate portion 174 with fastener hole 176 and an rear striker plate mounting plate portion 178, fastener holes 180 and a striker mounting portion 182, angled to enable mounting of a striker 212 thereon (not shown in FIG. 7 , visible in FIG. 24 ). The lower and striker mounting portions can be suitable, for example, for rear door mounting, while the mounting bracket 148 and striker plate 160 would be used for a front door mounting, in the case of an UTV/ATV having front and rear doors, used when both front and rear mesh ‘doors’ are being replaced.

Referring now to FIG. 8 , the process of mounting doors to an UTV/ATV in accordance with the invention is discussed. In FIG. 8 , a passenger side perspective view of an UTV/ATV 184, a first step is to remove the stock mesh doors by removing the mounting hardware thereof at positions indicated by arrows 186. Also, the front and rear mesh door latches are removed at positions 188. Mounting hardware at positions 190 are also removed, to allow removal of the doors, but at these positions the hardware is then returned into the mounting holes once the mesh doors have been removed, for use later in the process.

Next, the factory arm rests are removed from the UTV/ATV, the front driver arm rest 192 (FIG. 9 ) is removed by temporarily removing the seat mounting hardware at 194 (FIG. 10 ), and removing the fasteners at 196 in FIG. 11 , allowing the arm rest to be detached from the seat. The fasteners removed at 194 and 196 are then returned to their mounting holes.

The rear and front passenger arm rests are removed in accordance with FIGS. 12 and 13 , wherein upper mounting bolts 198 is removed and then lower mounting bolt 200 is removed, allowing the arm rest to be taken off.

Now, with reference to FIGS. 14-16 , filler panels 202 are removed from the front and rear passenger side of the UTV/ATV, and the mounting bolts 204 thereof are returned to their mounting holes.

Now, as shown in FIGS. 17 and 18 , the front and rear lower brackets 148 and 168 are mounted to the UTV/ATV, both on the driver side and the passenger side. In some cases this mounting may be done using the reserved factory hardware 150 from FIG. 17 , to mount the brackets, depending on the specific configuration of the UTV/ATV. The fasteners are just loosely tightened at this time. In the UTV/ATV configuration illustrated, the front most of the 2 mounting holes 150 in the front bracket are used for the mounting fastener, whereas the rear most mounting hole 170 is used for the rear brackets.

Referring now to FIG. 19 , the hinge assembly 100 may be mounted to the UTV/ATV frame by using the mounting hardware 198 reserved in the step shown in FIG. 12 to secure the shorter upper portion 112 of frame mounting plate 102 to the UTV/ATV frame via mounting holes 116 and 118 of the hinge assembly. While the mounting hardware 198 is loose, the hinge assembly is positioned such that a gap at the upper and lower portion thereof is about equal, and then the hardware 198 is tightened to secure the hinge assembly to the UTV/ATV. One such hinge assembly is mounted to the UTV/ATV frame for each of the doors.

Now, referring to FIG. 20 , the is hinge plate is secured to the lower bracket 148 via a fastener that is passed through hole 114 in lower end of the flange portion 110 of the hinge and hole 158 in the lower bracket. This is repeated for the other doors (using hole 176 in rear lower bracket 168, for the rear doors). The hinge assembly is now fully mounted to the UTV/ATV.

Referring to FIGS. 21-24 , the reserved hardware from the front doors indicated at 186 in FIG. 8 , is used to mount the front striker brackets 160 to the UTV/ATV frame. For the rear striker brackets, referring to FIG. 22 , bolts 206 are removed from the UTV/ATV frame that mount the factory rear latch 208, and exposing fastener holes 210 (FIG. 23 ). The rear striker bracket is now mounted to the UTV/ATV frame by using fasteners through mounting holes 180 in rear striker plate mounting plate portion 178. Rear striker 212, first mentioned in connection with FIG. 7 , is visible in FIG. 24

Now the doors can be mounted to the UTV/ATV. Referring to FIGS. 25-27 , the doors are positioned at the frame of the UTV/ATV by moving the door into position and engaging the striker with the door latch 214 (FIG. 25 ). The UTV/ATV will now appear as shown in FIG. 26 , with the hinge assembly positioned in the inside faces of the doors at positions indicated at 216, 218. As shown in FIG. 27 , plural bolts/fasteners 220 mount the door to mounting plate 104 via mounting slots 126, 128, 130, 132. The door is now securely mounted to the UTV/ATV.

Adjustment of the door to fine tune the alignment thereof is accomplished by loosening the bolts in the mounting slots 126-132, and then repositioning the door. The two Latch Adjustment bolts on the door can be loosened to reposition the latch for adjustment thereof.

Once the doors are attached, the removed seat components may be reinstalled.

Accordingly, an improved method and apparatus for mounting doors to an UTV/ATV has been shown and described.
